Can Dogs Go Bald? Understanding Localized Hair Loss
Dogs don't go bald from genetics like people do; their "bald spot" is localized hair loss from salty food, lack of sunlight, over-bathing, follicle damage, poor nutrition, or fungal/mite/bacterial skin disease. Adjust diet and care, limit baths, ensure sunlight and parasite control, and see a vet for serious skin issues.
What to Do When Your Dog Is Losing Hair
Hair loss is the shedding of fur. In dogs it may be a follicle disease from self-trauma by scratching or chewing.
Why Hair May Not Grow Back After a Fungal Skin Infection
After a fungal skin infection clears, hair may stay thin because the follicles were destroyed, or simply because the skin is still healing. Good nutrition with B vitamins supports regrowth, but scarred follicles may never recover.
What Is Dog Folliculitis?
Folliculitis means inflamed hair follicles. Professionally, bacteria infect the follicle and the body inflames the spot to self-repair. Mild cases go unnoticed; most are a tug-of-war needing meds.
Is Dog Folliculitis Contagious to Humans? Should You Isolate?
Dog folliculitis is a clogging inflammation of the hair follicles that looks like blackhead spots; simple cases aren't contagious to people, but if pustules rupture and spread fungus or bacteria it can be. Basic hygiene makes human infection unlikely, and isolation isn't needed — though separate other pets briefly if you have several.
Why does my cat get black spots all over after ringworm healed?
Black spots after ringworm are usually from medication irritation or damaged hair follicles. Fungal infection causes keratinization and melanin buildup; some drugs also irritate skin. Get a vet diagnosis; medicated baths help recovery.
My cat has two bare patches on its tail that are also dark
From the photo, this looks like ringworm with damaged hair follicles. Medicated baths are advised after shaving the area, plus follicle-repair medication. Improvement usually takes about half a month, with careful skin care in the meantime.
My cat has a scabbed spot on its head I removed, and now a dark crusty patch by the eye that looks removable; what could it be?
From the photo, the cat's symptoms are likely from medication irritation and damaged hair follicles. A fungal infection, if untreated, can later cause keratinization and pigmentation. Some medications can also trigger this. Take the cat to a vet for diagnosis and targeted treatment.
Our cat has dandruff for no reason – not bald, not red – but under a Wood’s lamp everything glows green. We also have red marks on our skin, but the cat’s dandruff has been there a while and we didn’t notice red marks then. Is it ringworm?
Based on your description, a cat with a lot of dandruff but no hair loss and no redness is not necessarily ringworm - it could also be an early stage of ringworm. In the middle stage there is heavy hair loss, and the affected area becomes damaged and red from scratching; later it becomes generalized ringworm. A cat with ringworm shows signs such as red patches, patchy hair loss, red skin, scratching, scabbing, red bumps, and abundant dandruff. It is recommended to use a Wood's lamp, shining it on the affected hair follicles (not on the fur), but the lamp test may produce false positives and is not very accurate. Therefore, take the cat to the hospital promptly for a skin scraping and microscopic examination; once diagnosed, start targeted medication right away.
What are the brown-red spots on my dog’s skin?
From the photo, this looks like folliculitis, usually from excess oil and bacterial infection inflaming hair follicles. Control inflammation and eliminate the source: bathe regularly with mild dog shampoo, apply antibacterial medication (spray, lotion or ointment) per vet advice, keep the environment dry/clean and diet balanced, and supplement vitamins to boost immunity.
